Description

Technical Field

[0001] The utility model relates to the technical field of computer room air conditioners, and more specifically, to an intelligent control device for an air-conditioned computer room. Background Art

[0002] Some existing intelligent control devices for computer room air conditioners mostly adopt traditional control methods. These methods have certain limitations in data management and equipment monitoring. Usually, the connections between devices are mostly direct electrical connections in a point-to-point manner, which may lead to insufficient stability and reliability of the computer room air conditioner system in case of failures. Between the connection circuits of high-voltage electrical equipment and passages, there is a lack of effective fine control and insufficient maintenance support capabilities are provided.

[0003] In addition, the energy efficiency management of traditional computer room air conditioner systems usually has a low level of intelligence, resulting in uneven air distribution and limited adjustment capabilities, causing the computer room air conditioner system to possibly operate excessively in unnecessary areas, resulting in energy waste. Moreover, the connection between specific devices lacks effective signal conversion and isolation, which may cause signal interference and potential safety hazards. Summary of the Utility Model

The data exchange center device is communicatively connected to a central server. Through the communicative connection between the data exchange center device and the central server, centralized management and real-time exchange of data are achieved, facilitating the monitoring and analysis of the operation data of the entire computer room air conditioner. The data exchange center device is electrically connected to the data collector, and the data collector is electrically connected to the heat and cold host device, the air heat and humidity treatment device, the air delivery and distribution device, the cooling device, the electrical control device, and the monitoring and management device.

[0005] Furthermore, a wired main communication link and a wired redundant communication link are used to connect the data exchange center device and the data collector. When a problem occurs in the wired main communication link, the wired redundant communication link can seamlessly take over the data transmission task, avoiding instability or downtime of the entire system caused by a single point of failure and improving the reliability of the system.

[0006] Furthermore, the air delivery and distribution device is electrically connected to the air heat and humidity treatment device through multiple branch lines. The air heat and humidity treatment device is responsible for adjusting the temperature and humidity of the air. The air delivery and distribution device effectively delivers the treated air to various areas in the computer room. The multiple branch lines allow independent control of the air flow and temperature in different areas of the computer room, optimizing the air flow, improving the energy efficiency of the air conditioning system, reducing energy waste, meeting the specific needs of different areas, and the design of the branch lines can isolate the faulty area to ensure the continued normal operation of the air conditioning system in other areas of the computer room.

[0008] Furthermore, the weak electrical control device is electrically connected to the electrical control device through at least one signal converter 821 to achieve signal matching and conversion.

[0009] Furthermore, the data exchange center device has at least one fault detection and recovery mechanism to maintain a stable connection with the data collector.

[0010] Furthermore, the electrical connection between the data collector and the monitoring and management device further includes at least one signal isolation layer. The design technology of the signal isolation layer includes one of optocoupler isolation technology, transformer isolation technology, capacitor isolation technology, magnetic coupling isolation technology, optical fiber isolation technology, digital isolator technology, analog isolator technology, and isolated power supply technology.

[0011] Furthermore, the strong electrical control device is electrically connected to the weak electrical control device through multiple relays. The relay uses an input electrical signal of the weak electrical control device to control the on / off of one or more output circuits, thereby realizing the control of high-voltage or high-current circuits on the path of the strong electrical control device.
